Which he does not do. He develops cryptographic libraries (used to encrypt files, network connections and the like). Nothing to do with cryptocurrency at all, save some cryptocurrencies might use the library he writes, but most of the use will be for TLS connections, file encryption etc.
If your definition of "crypto bro" is so broad to include "receives money from any person or company that has ever incidentally done anything with cryptocurrency" you've basically painted the entire industry that way.
Just because it mentions "Filecoin, whatever that is" doesn't imply that he's working in cryptocurrency.
I use "crypto bro" to describe people who actively work/invest in cryptocurrency directly and/or evangelize it. This usage does not intersect with Filippo at all.
But Filecoin IS a cryptocurrency. It's not merely "incidental".
Or change my mind and show me which of his projects is cryptocurrency-specific.
